Aist 1/2 (RS-41/43) Active on 435 MHz

AIST Microsatellite

AIST Microsatellite

On his website Dmitry Pashkov UB4UAD reports transmissions on 435.215 MHz and 435.265 MHz from the Russian Aist microsatellites developed by a group of students, postgraduates and scientists of Samara Aerospace University in cooperation with TsSKB-Progress.

Aist 2 (RS-43) on 435.215 MHz was launched first on a Soyuz-2-1a with the Bion-M 1 satellite on April 19, 2013. Aist 1 (RS-41) on 435.265 MHz launched later in the year on a Soyuz-2-1v Volga on December 28, 2013 .

A Google English translation of Dmitry’s post reads:

Since January 3, on board small spacecraft “Stork” at a frequency of 435.215 MHz and 435.265 MHz. are broadcast New Year’s greetings from the band “Samara Space Center.” The campaign will last until January 15, 2014.

Currently in orbit working group of two small spacecraft “Stork”, designed to meet the educational, scientific, technical and experimental problems. Staff spacecraft (frequency 435.215 MHz) was launched 19 April 2013, experienced spacecraft (frequency 435.265 MHz) was launched on 28 December 2013. Telemetry data from both satellites regularly supplied to the command post of the Centre for receiving and processing information “Samara Space Center.”

SkySat-1 satellite sends first HD video

Ching-Yu Hu - Skybox Imaging

Ching-Yu Hu – Skybox Imaging

Skybox Imaging was founded in 2009 by radio amateur Julian Mann KI6OSO along with Ching-Yu Hu, Dan Berkenstock and John Fenwick.

Many of the Skybox Imaging executives worked on CubeSat projects while students at Stanford University under Professor Bob Twiggs KE6QMD.

SkySat-1, the first in a planned constellation of 24 microsatellites, was launched on a Dnepr from Dombarovsky near Yasny on November 21, 2013. It is believed to be the smallest satellite ever flown that is capable of capturing imagery at better than 1 meter resolution and the 1080p HD camera can capture up to 90 second video clips at 30 frames per second.

The University of New South Wales (UNSW) has declared its undergraduate student amateur radio satellite project BLUEsat is complete and ready to be launched into space.

As the official final green light came it was to have a stratospheric balloon test flight near Wagga Wagga in New South Wales. Talks continue on a space launch date.

BLUEsat, a 260mm cube weighing around 13 kilograms, will carry a flight computer with transmissions to include a beacon and amateur packet radio using the AX.25 protocol in a “mode J” VHF/UHF configuration.

Magnets will passively stabilise the satellite and align it with the Earth’s magnetic field, and it will be controlled via a dedicated communications groundstation VK2UNS at UNSW is equipped with a Yaesu FT-847 satellite transceiver.

It is hoped BLUEsat will be placed in circular orbit at an altitude of around 750 km that will take it over the poles. At this altitude, the satellite will travel around the Earth at a rate of around once every 90 minutes.

Once in orbit BLUEsat will be a digital amateur radio satellite, which means that voice and data files can be uploaded to it by any amateur radio operator in the world over which the satellite passes.

Students from UNSW will continue to be the primary operators of the satellite while it is in orbit and continue the educational focus throughout the full satellite lifecycle.

Through sponsors helping to pay the bills the student-led project has given a space experience that includes VK2UNS the ground control station.

KiwiSAT – All systems are now flight ready

AMSAT-ZL KiwiSATThe KiwiSAT website reports that all hardware is complete and the KiwiSAT micro-satellite is operational. Final integration to launch ready awaits completion of command and control testing.

They say software is being developed and launch negotiation is underway in New Zealand. Earlier reports indicated that $1 million was required for a launch to a 700 km orbit.

SpinSat Packet Radio Satellite To Launch Next Summer

SpinSat comprises a 19 inch diameter sphere, with a mass of 55 kg and 4 antennas equal distance around the equator. It is intended to be a tumbling satellite with single axis momentum wheel and multiple micro-thrusters.

It aims to test new technology micro-thrusters and teach high school students about satellite operations.

Secondary mission is a 9k6 GFSK UHF store and forward AX.25 packet radio system with 2 watts of RF output. Planned for a July 2013 launch from Kennedy Space Center into a 330 km 51.6 degree inclination orbit.

A downlink frequency of 437.230 MHz has been coordinated.

PRISM Available for Amateur Radio AX.25 Packet

Overview of the PRISM Ham Radio Service – Image Credit Tokyo University

The team that developed the PRISM satellite have announced it is being opened up for use by radio amateurs during afternoon passes.

The satellite was built by the University of Tokyo and launched on January 23, 2009 into a 660 by 670 km orbit. It uses AX.25 packet radio and can now be used by amateur radio operators as a store-and-forward message box.
